According to TMW, Norwich City have made an offer for Quintero, the Colombian international playmaker who currently turns out with Porto.
The attacking midfielder, regarded as an exciting forward with strong technical skills and an eye for goal, has been offered a two-year deal by the Canaries, although he is also waiting upon an approach from Chievo Verona in Italy - who have registered an interest in him.
The midfielder, 22, has played for Envigado, Pescara and Nacional before his spell with Porto, with whom he has played 64 games. He has scored seven and created 11 goals in that spell, as well as scoring one goal in 13 games for Colombia.
Quintero played 30 times last season, as he struggled to hold his place down in Porto’s first-team, and with just two years left on his contract, the Portuguese giants may be willing to sell him if Norwich’s offer is suitable.
There are not yet any indications if Quintero is willing to move to Carrow Road, or even if he wants to leave Porto this summer.
If Norwich can agree a deal with Quintero, he would become the East Anglian club’s fifth signing of the summer, following deals for Graham Dorrans, Youssouf Mulumbu, Robbie Brady and Jake Kean.
